Product Description:

Bosch Rexroth manufactures the 2AD160B-B35RA1-BS03-B2V1 which is 3-Phase Induction Motors for industrial drive applications. It offers a nominal current of 72 A which enables efficient operation under continuous load conditions.

The 2AD160B-B35RA1-BS03-B2V1 motor provides a nominal torque of 191 Nm ensuring stable torque output for demanding processes. Its junction box is positioned on side A allowing a straightforward power connection. The motor delivers a medium air volume of 1120 m³/h. It uses an incremental encoder with 2500 increments for accurate speed and position monitoring. The rated power of 30 kW can be used to facilitate heavy duty activities with high levels of operational reliability. It is constructed to have the versatility of flange and foot mounting. The vibration severity grade R ensures mechanical stability during extended operational cycles. A maximum speed of 4500 min⁻¹ enables it to handle variable speed applications with consistent performance. It employs an axial blower cooling system to maintain thermal stability under continuous operation. The 205 kg mass highlights the motor's solid and durable construction. Its heavy-duty bearings support long service life under high radial and axial loads. The 2AD160B-B35RA1-BS03-B2V1 motor power terminal is located on the right for organized cable routing in control cabinets. The output shaft has an entire key balanced with a shaft sealing ring to offer accurate torque transfer. A thermal time constant of 60 min allows consistent heat dissipation during prolonged use. It offers reliable performance with its heavy-duty bearings and robust 305 V nominal voltage capability.

The 2AD160B-B35RA1-BS03-B2V1 motor nominal voltage is rated at 305 V. It operates reliably in ambient temperatures ranging from 0 to 40 °C. Its rotor inertia of 0.174 kg·m² supports stable acceleration and deceleration characteristics. The average sound pressure level is 75 dB(A) at one meter for acceptable noise control in industrial areas.
